Problems solved by technology

However, in the blending modification of ABS and PMMA, since ABS and PMMA are partially compatible systems, direct use of ABS and PMMA for modification and granulation is likely to cause uneven distribution of the two in the alloy, resulting in uneven surface hardness of alloy products

Embodiment 1

[0016] Weigh ABS and PMMA raw materials according to the weight ratio of 100:25, add 3.8 parts of MBS after mixing, then mix evenly in a high-speed mixer, transfer to a twin-screw extruder to melt and blend at 180-220°C, pressure 60- 80Mpa, the material stays for 2 minutes; the material is discharged, cooled, dried and pelletized after extrusion to obtain the finished product.

Embodiment 2

[0018] Weigh ABS and PMMA raw materials according to the weight ratio of 100:30, add 5 parts of MBS after mixing, then mix evenly in a high-speed mixer, transfer to a twin-screw extruder to melt and blend at 180-220°C, pressure 60- 80Mpa, the material stays for 2 minutes; the material is discharged, cooled, dried and pelletized after extrusion to obtain the finished product.

Embodiment 3

[0020] Weigh ABS and PMMA raw materials according to the weight ratio of 100:27, add 4 parts of MBS after mixing, then mix evenly in a high-speed mixer, transfer to a twin-screw extruder to melt and blend at 180-220°C, pressure 60- 80Mpa, the material stays for 2 minutes; the material is discharged, cooled, dried and pelletized after extrusion to obtain the finished product.

Abstract

The invention relates to a method for improving the compatibility of ABS and polymethyl methacrylate. The method is to fully mix 100 parts of ABS, 25-30 parts of PMMA and 3.8-5 parts of MBS calculated by weight ratio, and then use Melt blending extrusion one-step preparation. The method provided by the invention has simple process and low cost. MBS is added to the ABS / PMMA alloy system as a modifier, so that the two-phase system is evenly distributed after ABS and PMMA are granulated, and the compatibility between them is improved. , the surface hardness distribution of the obtained ABS / PMMA alloy is uniform, and at the same time endows ABS with more excellent tensile and bending properties, expanding the industrial application range of ABS.

Description

technical field [0001] The invention relates to the field of thermoplastic resin compositions in polymer material technology, in particular to a method for improving the compatibility of ABS and polymethyl methacrylate. Background technique [0002] ABS (Acrylonitrile Butadiene Styrene, acrylonitrile-butadiene-styrene copolymer) refers to a terpolymer composed of acrylonitrile, butadiene and styrene. Because ABS has good molding processability, the surface finish of the product is high , and has good paintability and dyeability, can be electroplated into various colors, combined with excellent performance, reasonable price and easy processing and molding, it has become the thermoplastic engineering plastic with the highest output and widest application. It is widely used in the automotive industry, Electrical and electronic industry, light industrial appliances, textiles, construction and other industries. [0003] Due to the low surface hardness of ordinary ABS products co...
